.To all. whom it may concern..-

Be it known that I, EDW RD A. SoHN, a citizen of the United States, and'a resident of Bedford, in thecounty of Lawrence and State of Indiana, have invented a new andImproved Derrick, of which the following is a full, clear, and exact description. a

The invention relates particularlyto aderrick involving a mast and boom arranged to turn bodily, so that the load may be lifted tained derrick and avoiding the usual practice of leading the boom and fall lines from the derrick to a power-house located at some more-or less distant point from the derrick..

The invention involves certain special features of construction and relative arrangement of parts, all of which will be set forth hereinafter, and particularly pointed out in the claims. I

' Reference is to be had to the accompanying drawings, which illustrate, as an example, the preferred. embodiment of the invention, in which drawings like characters of reference indicate like parts in the several views, and in which- Figure 1 is a rear elevation showing the motor, the gearing partly in section, and the foundation on which the derrick is mounted and the lower part of the mastof the derrick. Fig. 2 is a side elevation with the stepbearing of the derrick in section, this view showing the lower part of the mast and lower part of the boom. Fig. 3 is a'front elevation of the derrick, and, Fig. 4 is a sectional plan on the line 4 4 of Fig. 2. I indicates the foundation or body on which the derrrick is placed. As shown best in Fig. 2, this is provided witha suitable stepbearing 11, in which is received a center stud 12,

fastened to and projecting from the lower side of the table 14 of the derrick. On said table is arranged a suitable framing which is pref erably formed of side sections 15, carryinga: step 16 for the mast 17. Said side sections of the frame have projecting lugs 15, (seek Figs. 2 and 3,) to which the jaws 18 of the boom 19 are pivoted, so as" to allow the boom to swing from vertical position alongside of the mast downwardly into essentially hori-' zontal position. The mast is intended to be braced or guyed atits upper end in the usual manner, and thedevice for effecting this result is not illustrated. It will. be observed,

therefore, that the table 14, with its connected mast and boom, is free to turn around the center of the stud 11, and this table carries. the motor and .the gearing incident thereto,

as will now be described.

The motor 20 is preferably electrical and is 'indicatedby full lines in Fig. 1 and broken lines in Fig. 4, it being mounted on the table 14, as shown. motor is carried a pinion 21, (see full lines in 1 and broken lines injFig. 4,) and this plnion is in mesh with a pinion'22, fast on the main driving-shaft 23. This shaft extends horizontally over the table and is suitably On the armature-shaft of. the

mounted in one of the side portions 15 of the frame at one end of the shaft and in a pedestal 24 at the other end of the shaft,which pedestal rises from the table 14. In this manner the main shaft 23 is continuously driven during the operation of the motor.

Mounted loosely on the shaft 23 is a pinion 25, which is attached to a clutch member 26,

also loose on the shaft. Said clutch member is provided with a brake-band 27, encircling the periphery of the clutch'member, and said brake-band is actuated bya foot-lever 28.

Splined on the shaft 23 is a clutch member 29, which .coacts with the clutch member 26 to connect said clutch member 26 and the gear' in mesh with a spur-gear 36 on the shaft 37-of :a boom-fall-line drum 38. 39 indicates the boom-fall line, which passes from the drum wind the fall the boom may be dropped. The

38;up'along the mast and which is rove over suitable pulleys on the mast and boom, so that by hauling in on the drum 38 the boom may 4be raised and by permitting the drum to unshaft 23 also carries loosely a pinion 40,which is fastened to a clutch member 41, similar to the clutch member 26.

42 indicates a brake-strap coacting with the outer periphery of the clutch member 41, and 43 indicates a. foot-lever for actuating the brake.

Splined on the shaft 23 is a clutch member 44, eoacting with the member 41 and provided with any suitable means for actuating it for example, a lever 45,connected by a link 46 (see Fig. 4) with a hand-lever 47. By operating the clutch member 44 the gear 23 may be connected with or disconnected from the main driving-shaft.

The gear 40 is in mesh with a gear 48,which is loose on a counter-shaft 49, suitably mounted in the side portion 15 of the frame of the derrick. This counter-shaft 49 is located below, but essentially parallel with, the countershaft 34, before described. (See Fig. 2.) Splined on the counter-shaft 49 is a doublefaeed clutch member 50, which coacts with the two clutch members 51 and 52. These clutch members are loose on the shaft 49 and respectively carry a large gear 53 and a small gear 54'. Any desired means may be provided for shifting said clutch member 50-for exam ple, a lever 55, (see Fig. 3,) connected by a link 56 with a hand-lever 57. By so shifting the clutch member either one or the other of the gears 53 or 54 may be rendered fast on the counter shaft 49, which shaftis driven from the main shaft 23, subject to the action of the clutches 41 and 44, before de scribed. The gears 53 and 54 are in mesh with gears 58 and 59, which are fastened on a shaft 60, extending across the frame and having one end carried in one side part 15 thereof and the other end in a pedestal-bearing 61, which rises from the table 14. It will be seen that according to the position of the clutch member 50 the shaft 60 will be driven from the shaft 49 at a high or low speed, owing to the different ratio of the gears 54 and 59 and 53 and 58. A pinion 62 is loose on the shaft 60 and has a clutch member 63 connected therewith. Coacting with this clutch member is a clutch member 64, which is splined on the shaft 60. The clutch member 64 is operated to engage or disengage the clutch member 63, rendering the pinion 62 fast or loose on the shaft 60, as desired, and this clutch member 64 may be operated by a gear of any desired sortf0r example, a forked lever 65, connected by a link 66 with a hand-lever 67. The pinion 62 meshes with a spur 68, fastened on the shaft 69 of the fall-bloek-line drum 70. In Fig. 2, 71 indicates said line, which operates the tackle at the end of the boom for raising and lowering the load. It will be observed that this drum may by the operation of the clutch 50 be driven at either one of two speeds and that by the operation of the clutch member 64 the gear 62 may be disconnected from the shaft 60, so as to render the drum 70 free and permit the load to bedropped at will. The shaft 69 of the drum 70 carries a brake-wheel 72, through which a suitable strap and foot-lever 73 operate, permitting the drum 7 0 to be controlled at all times.

The main driving-shaft 23 carries at the end opposite the motor 20 a gear 74, which is in mesh with a gear 75, carried on a short hori- Zontal shaft 76. (See Fig. 1.) This shaft 76 has a worm 77 attached thereto, (see Figs. 1 and 4,) and the worm 77 is in mesh with a worm-wheel 78. The worm-wheel is carried on a revoluble shaft 79, extending along one side portion 15 of the frame. This shaft 79 is provided with two loosely-mounted bevelgears 80, meshed with opposite sides of a gear 81, which last-named gear is keyed to the upper end of the shaft 82.

80 indicates double friction member splined to the shaft 79 and movable by any suitable device to engage either of the gears 80, thus fixing one or the other to the shaft.

The shaft 82 is revolubly mounted in a bracket 83, depending from the table 14, (see Fig. 3,) and carries at its lower end a pinion 84, which meshes with a gear-ring 85, fastened to the bed or foundation 10, on which the derrick is mounted. In this manner by shifting the gears 80 to fasten one or the other of said gears to engage the shaft 79 the shaft 82 may be revolved in either direction and thepinion 84 caused to climb around the gearring 85, revolving the table 14 bodily with all of its attachments in either direction.

Tn the operation of the derrick the operator or operators stand on the platform and control the motor and the various clutches and brakes by the hand and foot levers provided therefor, and in this way the boom 19 may be raised or lowered and the hoisting or fall rope 71 Wound or unwound from the drum 70 at will, and the entire derrick may be swung bodily around the center pin or stud 12, so as to take the load from or deposit the load at any desired point. It will be seen that this arrangement provides a self-contained derrick which obviates the necessity of separate gangs of men to operate the derrick and hoisting-machine in the power-house, as heretofore commonly employed. It brings together in close juxtaposition all of the controlling elements and very materially reduces the labor involved.

While I prefer the motor 20 to be electrical, it is clear that steam or other power may be employed, if desired.

Having thus described the preferred form of my invention, I claim as new and desire to secure by Letters Patent 1. The combination with a framing mounted to turn, a motor carried thereby, a main shaft driven from the motor, a counter-shaft, a variable-speed connection between the main shaft and the counter-shaft, a hoisting means, a
